This week we're diving into the topic of combatives, and it would be hard to find a more qualified guest to discuss the topic than the one we have today. From bare-knuckle boxing the ROK Marines' Taekwondo champion to establish the US Army Combatives School, he has done it all.

Matt Larsen is a former United States Army Ranger and combatives instructor. He is known as "The Father of Modern Combatives," credited with the creation of the United States Army's modern combatives doctrine and the establishment of the U.S. Army Combatives School.

Larsen enlisted in the United States Marine Corps as an infantryman in 1984. He was stationed overseas in Kanagawa Prefecture, Japan with the Marine detachment at Naval Air Facility Atsugi. During this time Larsen began training in judo, Shotokan karate, and traditional boxing.

During his time in Japan Larsen fought in the Japan Karate Association's All Japan Karate Championships, Muay Thai bouts in Thailand, and a bare-knuckle fight against the ROK Marines Taekwondo champion. He was also a member of the 3rd Marine Division's boxing team.

Matt then transitioned from the Marine Corps to the Army and made his way to Ranger Regiment. Initially assigned to 1st Ranger Battalion at Hunter Army Airfield, Larsen parachuted into Panama with the Rangers during Operation Just Cause and was also involved in Ranger operations during the Gulf War.

After moving to 2nd Ranger Battalion he found himself as the Non-Commissioned Officer in Charge of combatives and Close Quarters Battle (CQB) and started developing a more formal curriculum. This led him to taking over the combatives program for the entire regiment.

During an assignment to 11th Infantry Regiment he establish a combatives schoolhouse in a warehouse. Within a short time, the school became so successful that units from throughout the Army began sending their soldiers. Several new courses had to be developed in order to continue teaching beyond the initial course, with the idea of building programs within these units. Eventually the school was recognized by the Army as the "United States Army Combatives School". In 2002, the training manual which he had been working on since his time with the Ranger Training Brigade was published by the Army as Field Manual 3-25.150 (Combatives).

After more than a decade leading combatives for the Army he now works at West Point's Department of Physical Education as the director of their combatives program.
